A town has a population of 17000 and grows at 3% every year. To the nearest year, how long will it be until the population will reach 20400

The population will reach 20,400 after 6 years.

Step-by-step explanation:

Exponential function:

y(t)= Population after t years

= initial population

r= rate of grow

t= time.

A town has a population of 17,000 and grows at a rate 3% every year.

y(t)= 20,400, = 17,000, r=3%=0.03, t=?

Taking ln function both sides

⇒ t = 6 year.

The population will reach 20,400 after 6 years.

x=18, m∠1=140, m∠2=40

Step-by-step explanation:

m∠1 and m∠2 will equal up to 180

7x+14+2x+4=180

Combine like-terms

9x+18=180

Subtract 18 from both sides.

9x=162

Divide both sides by 9

x=18

Then plug in 18 for x in the angle measures

7(18)+14=140

2(18)+4=40
